What is the BTU size of the furnace that’s being proposed?

Furnaces are designed to
provide specific amounts of heat energy per hour. The term ”BTUH” refers to how
much heat can be produced by the unit in an hour. Before you can determine what
size furnace you’ll need, you must have a heat loss/heat gain calculation done
on the structure. From that, an accurate determination can be made of the size
of the system you’ll need. Most
fossil fuel furnaces are substantially oversized for heating requirements,
resulting in increased operating cost and unpleasant temperature swings.
